Celebrate Brooklyn: Salif Keita & Haale

Sunday, Jun 22, 20086:00 p.m.Brooklyn

Celebrate Brooklyn presents Salif Keita & Haale.

Known as the “Golden Voice of Africa”, KEITA blends the traditional griot music of his own Mali with sounds from Guinea, the Ivory Coast, and Senegal, along with influences from Cuba, Spain, and Portugal. “Keita’s voice leaps out of every song with tender urgency.” (NY Times) Persian rock goddess HAALE’s enchanting vocals soar over her band’s amplified rumble, which serves “as a reminder of the extent to which rock bands like the Doors and the Velvet Underground turned to the East for their hypnotic efforts.” (NY Times)
